Fight takes place in the streets of New York:

Everyone have standard equipment. Morals are off.

Bump

Clears

stops at round 6

I wish I remembered more about Ra's Al Ghul, but I'm willing to say they stop at round 7. Bane is heavily underestimated and, contrary to popular opinion, showed decent speed in TDKR.

Widow solos the first couple rounds, she just shoots all of them. The last few could be a little rough for the team but they clear.

Stops at 7

Not sure why Bane would be an issue really, Widow shoots him and the ninjas are fodder, regardless of how many there are.

Stops at 5 or 6

Clears.

Four ninjas was enough to challenge Batman, but he still won. Given that I think either could solo the first two rounds with just their H2H abilities. With full gear AND fighting together, they definitely clear, and an argument could be made for either winning on their own with full gear.

I don't think they can clear round 8.
